Campaigners against the use of Rotherhithe park King’s Stairs Gardens have said they are “relieved but cautious” after sewer bosses said they are keeping their options open.

Following the end of the public consultation in January, Thames Water is now looking at the viability of Chambers Wharf as an alternative location for the super sewer tunnel.

Roger Bilder of the Save King’s Stairs Gardens Group Action said: “We are pleased but we are still campaigning to demand Thames Water remove our park from the list of possibilities altogether.

“They need more than one alternative option and since the Daily Mail announced it would be moving away from Harmsworth Quays that site is another possibility.” Thames Water has purchased the land at Chambers Wharf which was due to be used as part of a development.

Phil Stride, Thames Water’s head of London Tideway Tunnels, said: “Finding suitable potential locations for our major shaft sites has been really difficult. As a result, and due to the fact Chambers Wharf previously had to be discounted from our proposals, we could only present people in the Bermondsey area with one option for their comments during the first phase of our public consultation.

“When Chambers Wharf came up for sale, we had to act quickly to ensure we could consider the land in detail as a potential site. It is vital that we keep our options open.”

The Save KSG Action Group is holding a meeting tonight at St Peter & the Guardian Angels Church Hall, Paradise Street, at 7:45pm.

The East End of London remembered its civilian war dead yesterday in what may well be the last annual remembrance of the 1943 Bethnal Green air raid disaster before a permanent memorial is finally in place.
